ABSTRACT:
The inclusion of an ester of dipentaerythrital and one or more C.sub.4 to C.sub.8 carboxylic acids in a composition comprising a silyl polymer and an organometallic silanol condensation catalyst, decreases the tendency of the composition to undergo premature crosslinking during the fabrication of articles therefrom. The invention includes compositions crosslinkable by the action of water comprising a silly polymer, the ester and an organometallic silanol condensation catalyst and also processes for the preparation of the compositions.
